427 knocking Alright
I have a 427 and missed 3rd and over revved it and a few weeks later it started knocking. Had to replace the valve train and lifters on the passenger side. Once I had everything replaced it is still making a knocking sound that sounds like it's coming maybe from the cam? I'm not a mechanic and I've had a lot of different story's on what is wrong. Just looking for some other opinions.

If you over revved it, there's a possibility that it's a bent pushrod. You said that you replaced the valve train on the passenger side, is the "knock" coming from the driver's side now?

Just financial reasons. And I didn't see any problems with the other lifters. You thinking its a lifter problem? And it's just a regular 427 set up with a fast 92 intake no other mods to the motor.
